Adjust the master valve of your sprinkler system by turning the flow control clockwise until the stream of water from the nozzle begins to drop. This lowers the water pressure. Turn the flow master valve flow control slowly until the spray pattern reaches its full radius.
How do you adjust the water pressure on a sprinkler head?
To adjust a stationary sprinkler head, find the spray radius adjustment screw on top of the nozzle. You may need to adjust it slightly to point the water spray in the direction of your lawn that you want it. Turning it clockwise can also help lower the water pressure on a spray head that is shooting too much water out.
How do I fix low water pressure in my sprinkler system?
If the pressure is low at only one or two sprinkler heads, they may simply be dirty. Examine the sprinkler head and filter and clean if needed. Grass can also grow around the base of the sprinkler heads and cause them not to pop up fully, so trim and clear away any obstructions.
Can a bad sprinkler valve cause low water pressure?
One of the leading reasons for low sprinkler water pressure relates to the valves on your backflow preventer device. If you notice limited water pressure in your sprinkler system but normal water pressure inside your home, then the problem might be that your backflow preventer valves are not completely open.
What is good water pressure for a sprinkler system?
Different types of irrigation equipment have different ideal operating pressures for maximum efficiency. For rotors, this is about 45 psi, with an operating range of 25 to 65 psi. For spray heads, it is 30 psi, with an operating range of 15 to 30 psi.
How do I water my lawn with low water pressure?
While sprinklers with misting or stationary (aka fixed) heads tend to perform better in low water pressure situations than those that move, you can still find rotating or oscillating sprinklers that can operate with water pressures under 40 PSI.
